You have some funny ideas on consent.
Tasha may have been the aggressor but she still wasn't in her full state of mind, it'd take an immoral person to take advantage of that. Plenty of times drunk women get in "aggressive" moods sexually and it's still pretty much universally considered dickish to take advantage of that.
If Data were a sexually mature human, and was aware that she wasn't in her right mind, that would be true. You chose to ignore the part where I said that Data was virtually a child when it came to sexuality.
Hypothetically, if a drunk woman seduces and has sex with a minor, who's at fault?
